R2, since that little fellow is dangerous. I bet it could hunt some food for me on the way.
I like both. But probably C-3PO .... he reminds me of a golden Sheldon Cooper.

Did either of them come with GPS?
C-3PO as he could probably converse with you on many topics, and I don't speak R2's language of buzzes and whistles, which would get annoying quickly...
